1、Designation:E2556/E2556M10Standard Specification forVapor Permeable Flexible Sheet Water-Resistive BarriersIntended for Mechanical Attachment1This standard is issued under the fixed designation E2556/E2556M;the number immediately following the designation indicates the yearof original adoption or,in
2、 the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification is limited to vapor permeable flexiblesheet materials which are inten
3、ded to be mechanically attachedand are generally installed behind the cladding system inexterior walls.1.2 This specification is limited to the evaluation of mate-rials and does not address installed performance.Although thefastening practices(type of fastener,fastening schedule,etc.)may affect the
4、installed function of these materials,they are notincluded in this specification.1.3 This specification does not address integration of thewater-resistive barrier with other wall elements.The topic isaddressed in more detail in Practice E2112 and Guide E2266.1.4 The values stated in either SI units
5、or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 This standard does not purpo
